Ubuntu – Frozen on Installer Boot Menu

system-installation

I am attempting to install ubuntu from a USB flash drive onto an old laptop with Windows XP. "Install Ubuntu" is highlighted in blue on the Installer boot menu and I have pressed Enter. 40 minutes later the screen still shows the Installer boot menu with Install Ubuntu highlighted and when I press any key, including escape, the computer beeps and nothing happens. What do I do now? Can anyone please help.
